yes. because the normal bulb load involve only resistor. the direction of source is not considered
No, a 48-volt DC power supply cannot directly power a 100-watt AC bulb. AC bulbs are designed to operate on alternating current, typically at standard voltages like 120V or 240V, and require an AC waveform. To use a 48-volt DC supply, you would need a compatible DC bulb or a DC-AC inverter to convert the DC to AC at the required voltage and frequency.
AC...
we can check the dc with the help of tester give the reasonAnswerThere is no such thing as an 'AC light bulb' and a 'DC light bulb'. A light bulb doesn't care whether it is subjected to AC or to DC.
The type of power supply being used (AC or DC) should match the power requirements of the device it will be supplying power to.
No. A bulb can run a AC just a easily as DC.
It can be operated using both AC or DC
In AC supply, the RMS current is the effective current for power used in a resistive circuit. This is defined as the square root of the mean value of the square of the current, taken over a whole cycle. The RMS current dissipates power at the same rate as a DC current of the same value. A light bulb of course gives out light dependent on the current through the filament. So if the RMS current and the DC current are the same value, the light produced will be equal. With AC supply, the RMS value of current and volts is 1/(square root of 2) x the peak value, so peak value = 1.414 x RMS value. If you supplied DC at volts and current equal to the peak AC value, the power given to the light bulb would clearly be greater. Therefore to answer your question you have to specify what relative values your AC and DC supplies have.
When you connect a load (motor, light bulb, etc.) in series with a power supply, current will flow, whether AC or DC depends on the power supply you are using.
The voltage source that is applied to them is the difference between AC and DC light bulbs.
A DC to DC converter is basically a type of switching power supply. The switcher converts the input DC to AC. A transformer is used to convert the AC to the desired voltage. A rectifier, filter, and optional regulator is used to convert the AC back to DC.
we can convert a dc supply to an ac supply using inverters. Its a common operation which we observe in our daily lives dc can be converted to Ac using an undulator.
the universel motor can runs at both ac and dc supply.
